ATOMIZER.

SPECIFICATION forming part of Letters Patent No. 507,581, dated October31, 1893.

Application tiled November 18. 1892. Serial No. 452,403- (No model.)

T0 @ZZ whom t may concern:

Be it known that I, FRANKLIN B. GIESLER, a citizen of the United States,and a resident of Milwaukee, in the county of Milwaukee, and in theState of Wisconsin, have invented certain new and useful Improvements inAtomizers; and I do hereby declare that the following is a full, clear,and exact description thereof.

My invention has for its object to provide a simple and eicientatomizer, especially designed for use in connection with pneumaticmalting apparatus; and it consists in certain peculiarities ofconstruction and combination of parts hereinafter described withreference to the accompanying drawings and subsequently claimed.

In the drawings: Figure 1 represents a vertical transverse section of anatomizer constructed according to my invention; Fig. 2, a plan viewpartly broken away and illustrating my device as it appears below line2-2 of the preceding figure; Fig. 3, an inverted plan view of the partsabove line 3-3 of Fig. l; Fig. 4, a view taken on said line 2 2 of Fig.1, looking upward, and Fig. 5, an elevation of the atomizer, set up inan air-duct and connected to air, water and steam inlet-pipes.

Referring by letter to the drawings, A represents the base of my devicein the form of a disk, and cast with or otherwise rigidly connected tothe upper face of this disk is a cup B having a central bottom opening binto which is iitted a valve-controlled pipe C that leads from a sourceof air under pressure. Seated onthe disk to surround the cup is a troughD having an opening c for the reception of a branch E that leads fromthe airpipe C above specied. The space d intermediate of the cup andtrough on the disk A communicates with a valve-controlled pipe F thatleads from a source of water supply, and the outlet from said space isin the form of a narrow channel e between the opposing v edges of saidcup and trough.

Fitted to the trough D is a cover-plate G held in place by means ofbolts f passed through itself, said trough and the disk A, as

5o best illustrated in Fig. l. The cover-plate has its under sideprovided wit-h a groove that engages the opposing edges of the cup andtrough on the disk A the area of this groove being such that the resultof said engagement is a channel h that communicates with said cup andtrough and has its outlet in the form of ports t' cut in the groovedportion of said cover-plate to register with the channel e abovespecified.

The upper face of the cover-plate is provided with a collar j beveledou'tward upon its inner side from the outer line ofthe ports z', andextended up from the center of said plate is a hollow boss lc that isfitted at its upper end to a steam-pipe H and has its lower end providedwith lateral portsm leading into a chambern formed bythe aforesaid plateand a hollowed or conical cap I, which latter engages the boss lo and isheld in place by means of jam-nuts o, p, engaging screwthreads cut onsaid boss. The cap I is provided with vertical lugs q that rest on thecover-plate G, above specified, and the outer edge of said cap isbeveled parallel to the inner face of the collar j on said plate. Byhaving the cap provided with the supporting lugs q I obtain spaces orports 1' intermediate of said cap and the cover-plate G for the es# capeof steam from the above described chamber fn, and the greatest diameterof the aforesaid cap being less than that of the collar j on saidcover-plate I obtain a channel s between ythe opposing beveled faces ofthese parts, this channel being in direct register with the one e andthe ports e' hereinbefore set forth.

From the construction and arrangement of parts as defined in theforegoing it will be readily seen that there is .an equal pressure ofair on opposite sides of the channel e and that waterlet into the spaced, intermediate of the cup B and trough D, will be mingled with the airand converted into vapor, thisV vapor having its escape through theports Il and channel s in register therewith.

For the purpose of raising the temperature of the moist air or vapor,steam is let on through the pipe H to escape through the lateral portsm, of the hollow boss k, into the space n and from thence through theports 1' IOO to mingle with said moist air or vapor at the intersectionof the ports il and channel s, the product of the intermingled air,water and steam having its escape through the latter channel. Thischannel s being divergent, the discharge therefrom is deected from theatomizer and thoroughly distributed.

Vhile the atomizer herein set forth is more particularly designed forsaturating, heating or both of the air admitted to apneumatic maltingapparatus, it may be utilized for vaporizing fluid other than Water.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An atomizer comprising two concentric air-spaces connected by asuitable channel, an intermediate fluid-space having an outletcommunicating with the channel, and a final outlet in register with saidchannel, substantially as set forth.

2. An atomizer comprising two concentric air-spaces connected by asuitable channel, an intermediate fluid space having an outletcommunicating with the channel, a final outlet in register with saidchannel, and a stea1ndischarge communicating with the latter outlet,substantially as set forth.

3. An atomizer comprising a base provided with a cup having an openingfor communication with a source of air under-pressure, a trough on thebase surrounding the cup and also provided with an opening forcommunication with the source of air under pressure, a chamber that isbounded by the base, cup and trough, but has an opening forcommunication with a source of water-supply and is provided with anoutlet between said cup and trough; a cover-plate grooved to formachannel communicating with the aforesaid cup, 4o

trough and outlet; and ports formed in the cover-plate to intercept saidchannel, substantially as set forth.

4. An atomizer comprising a base provided with a cup having an openingfor communication with a source of air under pressure, a trough on thebase surrounding the cup and also provided with an opening forcommunication with the source of air under pressure, a chamber that isbounded by the base, cup and trough but has an opening for communicationwith a source of water-supply and is provided with an outlet betweensaid cup and trough; a cover-plate grooved to form a channelcommunicating with the aforesaid cup, trough and outlet; ports formed inthe cover-plate to intercept said channel, a collar on the cover-plate,a hollow boss extended up from said cover-plate to connect with asourceof steam supply and provided at its lower end with lateral ports; and ahollowed cap that is positioned on the boss and provided with supportinglugs resting on the aforesaid cover-plate, the greatest diameter of thiscap being less than that of said collar, whereby a channel is formedbetween the two in communication with the cover-plate ports and thesteam space intermediate of said cap and cover-plate, substantially asset forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.

FRANKLIN B. GIESLER.
